Switchport mode Access Changes to Trunk automatically

sumit.karki · ‎09-05-2018

I have a cisco Sf250 Switch, all are working fine except one port. I have made it to work as a access port but it keeps changing to Trunk port over time. I have switched ports but to no avail.

Any help is appreciated,

Thanks in advanced.

Hi sumit.karki

if DTP " dynamic trunking protocol " is enabled on both end , it will be converted to Trunk mode , so if you want to disable this , you have to disable DTP .

Hello

I haven’t worked on these type of switches but if you have made this an access port how does end up being Trunk?

switchport mode access should disable any dtp so not to do as you are saying?
